Storms can be tough on city channels, especially when urbanization changes how water flows. We've been using rules called the Unified Stormwater Sizing Criteria (USSC) to manage this, but it turns out they might not be keeping channels safe from erosion. So, let's dig into how we can do better. Fir
In the rushing waters of the Jinsha River, two types of bacteria – free-living (FL) and particle-attached (PA) – play crucial roles in shaping the aquatic ecosystem. Despite their shared habitat, these bacteria have distinct ways of merging their communities, a process called coalescence. Scientists
Emergency managers in California face a tough job when it comes to dealing with wildfires. They have to handle not just the fires, but also the other problems that come with them, like floods and landslides. Four main issues came up in discussions with emergency managers from nine California countie
Imagine the shock when Leslie Schmid and her husband woke up to find their home security camera had captured a nighttime visitor. A bear decided to take a dip in their swimming pool during a chilly night in Foresthill, California. The bear's cold-weather swim wasn't its first episode, as it had visi
Volcanic areas are some of the most active places on Earth, but we don't understand them very well. Let's look at the central Cascade arc in the USA. Here, water and landforms change together in a systematic way, linked to how old the volcanic rocks are. At the Cascade crest, where there's a lot of
It looks like California might be in for a rough few months. Weather experts have warned that the state is facing particularly dangerous wildfire conditions. What makes this situation unique? It’s the combination of dry fuels and powerful winds. Fuels are things like grass, shrubs, and trees that ca
In the wake of Donald Trump Jr's social media post suggesting a link between Ukraine and the California wildfires, Ukrainian President Volodymyr Zelenskyy has offered to send 150 firefighters to help. This comes as California faces one of its most devastating natural disasters, with entire neighborh
Water scarcity is a growing problem that will affect half of the world's population. It's not just about having enough water; it's about how it affects our health and daily lives. When water is scarce, people get sick from water-borne diseases, don't have enough to eat or drink, and can't work or go
You might think that recycling more or going vegan can save the planet, but the truth is, it's not that simple. Individual actions like these have a tiny impact compared to big systemic changes. For instance, even if everyone in the U. S. went vegan, it would only cut greenhouse gas emissions by 2.
Rivers around the world face big problems like pollution and damming. These issues threaten the lives of both people and animals that depend on rivers. To fix these problems, we need to work together in special places called River Co-Learning Arenas (RCAs). RCAs are like classrooms where different p
